Four hours after Ned left the starting point, where the portal randomly transported him somewhere on the island, Ned got 200 points. Just like that.
Ned's strategy was simple: hit and run.
In the four hours he has been traveling, Ned encountered a good number of candidates. Most of which were busy struggling with one another. Be it solo, or in a group.
While forcing his way amidst the chaos, Ned gained several enemies as well. Enemies he forcefully absorbed their Mana and put it into his own.
Ned also learned something about Storing Claims: if it was empty of Mana, no one, even him, could inject Mana as long as it wasn't his. This also means that if for some reason, his Storing Claim was to be stolen, he has to retrieve it no matter the cost. Another, thing: Storing Claims were extremely fragile. Without them breaking, Ned might already have 400 points.
